I haven't noticed a drop in my 3 star attacks to be honest. If anything they have been more consistent.
In the last few wars I have been running:
- GoHoWiWi
- GoVaLo
- GoLoWiWi
- GoWiWi
- GoWiPe
I haven't seen or heard any complaints from my clan mates about a drop of stars in their attacks either.
